Update.

Game:Far Cry 4.
Time:1 hour more or less.
Setting: low @ 1366x786
Frame:30[on camera] -72
*when zooming[on camera] the frame went to 30 but most of the time, it's smooth like 40 and above.
*using Idea Fan software. It did turn on the dust cleaning mode and it stop when temps when down.




The In-game sound helps drowning the fan noise.

but the temperature is still high
